UFO is a powerful ability that offers permanent levitation and four different attacks. The type of attack UFO Kirby does is based on how long the player holds down B. The longer it's pressed, the stronger the attack will be. Kirby is capable of moving around while charging, but cannot change the direction he is facing. UFO's main limitation is that Kirby cannot go back down through floors while having the ability, even with ladders.
In Kirby: Squeak Squad, should the player attempt to drag a bubble item from the Copy Palette up to Kirby's mouth while in UFO form, Kirby will comically flip upside-down and drop to the ground head-first, and cannot move as long as the bubble is within his mouth until he exhales it or re-swallows it. This will also happen with Ghost Kirby, but instead he will inflate and drop onto the ground. Trying to do this over a bottomless pit spells an instant KO.
In Kirby: Planet Robobot, UFO can be accessed by using the Kirby amiibo from the Kirby amiibo series or by completing the game 100%. The ability acts much like it does in Kirby: Squeak Squad, even retaining the Trajectory Orb, though it now has a new move that allows Kirby to beam up enemies with a tractor beam. This move can be compared to a similar move Kirby performs while in Saucer form in Kirby's Epic Yarn.
UFO Kirby's basic feature. It is identical to Beam's signature attack, although Kirby can move freely through the attack.
Hold B/A (Low hold)
Kirby fires a ricocheting laser beam. It is identical to Laser's attack.
None (But can light cannon fuses)
UFO Laser/Heat Beam
Hold B/A (Medium hold)
Kirby calls upon the power of his spaceship to strengthen his laser. It slightly stronger than his first laser attack, about equal in power to an inhaled and ejected enemy. However, this Laser cannot ricochet off walls.
UFO Wave Cannon/Piercing Heat Beam
Hold B/A (Long hold)
When Kirby conjures up enough power, he unleashes an electrifying energy beam. It is the strongest of his laser attacks. It also goes through walls. In Kirby's Adventure, the blast is in the shape of a star.
Hold B (Even longer)
Kirby uses most of the ships power to fire 3 beams in front and one beam behind him. The large beam is a larger Piercing Heat Beam, while the 3 smaller ones are that of the Heat Beam.
Dash + Hold B
Kirby disappears and reappears many times in a zig-zag shape forward.
Kirby creates a vortex under the ship, sucking in any enemy, similar to that of his UFO form in Epic Yarn
Trajectory Orb/Star Guard
Requires UFO Copy Scroll. A small ball of electricity orbits the UFO, and causes minor damage to anything it comes into contact with.
Hold down the B Button to charge, and then let go! You can attack four different ways!
Wow! I'm so lucky I copied a UFO! I can do four different moves. It all depends on how long you hold B!
Kirby's UFO is affected by Spray Paint, much like the Magic ability's hat. More specifically, the hull is the color that would be Kirby's shoes and the rest is the color that would be Kirby's body despite it being shown gold in the official artwork.
